Seal coating asphalt question - is big box stuff any good?

[Adam Craig]

Is there a big difference between the seal coating you purchase from big box stores compared to what asphalt companies use?

I notice Lowes and Home Depot carry several different grades of seal coating, similar to paint. The more expensive ones claim longer life span. I have had my handymen put down seal coating on a few occasions and I have hired asphalt companies many times. I save a little money having my guys do it but was wondering if we are using an inferior product?
